MTWB Solid Lubrication Bearings are engineered specifically for papermaking equipment, delivering reliable self-lubricating performance in the demanding environments characteristic of paper manufacturing operations. These bearings are designed for applications where conventional lubrication is difficult, impossible, or uneconomical, making them the ideal solution for the paper industry's unique challenges.
In papermaking machinery, dust, paper fibers, particles, moisture, and other debris constantly threaten bearing performance and equipment reliability. MTWB's solid lubrication technology effectively reduces intrusion of these contaminants, ensuring consistent operation and extended service life.
MTWB Solid Lubrication Bearings utilize an advanced polymer matrix technology. The polymer material is injected into the bearing in a specialized process, adsorbing saturated lubricating oil to ensure tight and continuous contact with raceways and rollers. The lubricating oil is "stored" in micro-pores within the polymer based on surface tension. During operation, a small portion of the lubricating oil slowly moves to the material surface through capillary action, and when operation stops, the oil re-adheres to the polymer for "storage". This innovative mechanism effectively prevents contaminants from entering the bearing interior while maintaining continuous lubrication.
| Parameter | Details |
|---|---|
| Lubricant Types | E mould, G mould, Type F2 (Food Grade available) |
| Ultimate Temperature | Up to 150°C – 200°C (depending on lubricant type) |
| Precision Class | P6 or above |
Note: Specifications can be customized to meet specific papermaking equipment requirements.
With polymer matrix adsorption saturated lubricant technology, lubricant seamlessly adheres to raceways and rolling elements without the need for an external oil supply system. Re-greasing is completely eliminated, reducing maintenance labor and downtime in paper mills. The embedded sealing design effectively prevents invasion of pollutants and improves water flushing resistance by 80%.
Solid lubricant content is 2-4 times higher than traditional lubricants. Bearing service life can be extended by more than 3 times, significantly reducing the frequency of spare parts replacement and minimizing production interruptions.
The solid lubricant maintains close contact with raceways and rollers, almost filling the entire bearing.
The remaining space within the body effectively prevents pollutants—including paper dust, fibers, and moisture—from entering the bearing, protecting it from contamination-related failures.
Lubricating oil is stored in micropores inside the polymer based on surface tension. During operation, oil transfers to the material surface under capillary action; when operation stops, oil is reabsorbed into the polymer for "storage". This prevents environmental pollution and product contamination caused by lubricating oil leakage—a critical concern in paper production.
MTWB Solid Lubrication Bearings are suitable for high ambient temperatures (up to 200°C), high humidity, dust, and chemical corrosion environments. The integral bearing seal further improves oil retention, while the excellent anti-rinsing capability ensures reliable performance even in wet papermaking conditions.
